Pleiotrophin has been identified in serum and lung cancer tissue or cell culture as a candidate lung cancer biomarker. Pleiotrophin was also observed up-regulated in lung cancer in this study. Others studies have suggested that pleiotrophin may be an early indicator of lung cancer and might be of use in monitoring the efficacy of therapy.

PTN, also known as pleiotrophin, is a member of a 12 protein panel that can discriminate NSCLC from controls with 91% sensitivity and 84% specificity in cross-validated training and 89% sensitivity and 83% specificity in a separate verification set, with similar performance for early and late stage NSCLC.

Analysis of the EDRN lung biomarker samples will enable the next step in development of a clinical diagnostic assay for the differential diagnosis of lung cancer or benign disease in patients with indeterminant pulmonary nodules. The objective is to develop a blood test with sufficient accuracy to identify lung cancer in these patients, which will aid the treating physician in decisions to recommend invasive procedures or watchful waiting.
